A fortnight after academics voiced their anger and handed over a 3000-strong petition, about 80 people joined a student-led protest which marched to the administration building.

Several speakers argued the $50 million deal was regressive, created a "bubble of privilege" on campus, and was a threat to academic freedom.

Politics lecturer Anthony Ashbolt said the privately-run and funded Ramsay school was part of "an ideological mission" which would "start corroding the university from inside".

"It is about cementing their interests in the power structure," he said.

"It's a private institution corroding our very public institution."

NTEU branch president Georgine Clarsen said academics remained offended at the lack of consultation before the deal was announced.

"It would insert a bubble of privilege into the public institution," she said.

"Wollongong is the only university which has not let academic have input into this decision making."
